WILLISS. RICHARDSON, or NEWARK, .NEW JERSEY.

To all whom it may concern..-

Be it known that I, WILLIS S. RICHARD- soN, a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have made and invented certain new and useful Improvements in Watchmakers Tools, of which the following is a specification.

My invention relates to an improvement in watchmakers tools.

In stores, shops, and other places wherein a number of watches are ke t or retained for regulation much time and labor are consumed in daily winding the watches by hand.

The object of my invention is to provide a device whereby this winding may be effected wit further, to so construct and arrange the several arts as to adapt it to the Winding of watchpls having crowns of different sizes.

Wit

these and other ends in view the invention consists in certain novel features of construction and combinations of parts, as

will be hereinafter fully described, and pointed out in-the claims.

In the accompanying drawings, Figure 1 is a top plan view of my improved device. Fig. 2 is a view in side elevation thereof. Fig. 3 is a front view of the spring-actuated Winding-arms. Fig. 4 is a sectional view of a part of the device.

Referring to the drawings, A represents the base-plate, adapted-to be secured to a bench or other support, and, as clearly illustrated in Fig. 2, may downwardly-extending lug B, whereby the tool may be clam ed in a vise or other place for the purpose 0 securely holding the same while in use. r

Extending upwardly from the base A are the plates or standards 0, having journaled in the upper ends thereof the shaft D, adapted to rotate therein, but prevented from endwise movement by means of the collar E, pinned or otherwise secured to the shaft. To is secured the handle F ose of rotating the same, the o posite en G of said shaft being threaded. T8) the extreme end of the shaft is fastened the plate H, rovided with the extensions h, preferably t ee in number, each of said extensions be' slotted and having pivoted ingarms I, the outer ends of which are ada ted to en age with the grooved or corrugate crown l of a watch, the engaging edges of said arms being beveled,

l as shown at k, to allow them to enter; the ooves or corrugations in said crown. hese three winding-arms I are connected by a spring L, the tendency of which is to open or spread a art the engaging ends of said arms and to (dose or spring together the rear ends of the same, which rear ends bear upon the nut M; threaded on the end G of said shaft D and preferably made in the form of a truncated cone, having the milled edge Nat the base thereof.

y turning the regulat' nut M in one direction-that is, toward t e extreme end of the shaftthe ends of the arms bearing thereon will he s read apart, closing or bringing together t e o posite or engaging ends of said arms, and w on the nut is turned and travels in the o the shaft the spring will operate to open or spread apart the engaging ends ,of said arms, at the same time retaining the opposite ends thereof in engagement upon the cone shaped nut M. v x

In practice the tool is fastened or secured in a vise or other proper support. The crown of the watch is then placed between the engaging ends of the arms I and the nut M turned until the beveled edges 7c of said arms enga e with the grooved or corrugated crown K. fiy turning the handle F and rotating be provided w1th the the shaft D the crown K is turned, the watch of course being held stationary in the operators hand, until the winding of the watch is completed. This operation can be effected with much less labor and in much quicker time" than is watches in the ordinary way by hand.

Having fully described my invention, what ters Patent, is

1. A watch-winding tool having bination a support, a shaft rotatable in comtherein,

ends of said arms to engage the crown of a watch.

I claim as new, and desire to secure by Let inwardly exosite direction upon 7 now consumed in Winding the having one end threaded and the opposite A watch-win bination a. supyontm having one end 'threadecl and the 'oppoute sions said extenions having 'end provided with means whereby ittmaytt rotated, a plate fastened to the extremityhof aft mtat athemm;
